About the Host

Rıdvan Yiğit is the Founder & CEO of RTC Suite — the world's first Autonomous Compliance and Payment Intelligence platform, built natively on SAP BTP and operating across 80+ countries.

For the past thirty years, the ERP has led and the tax function has followed. The ERP team defines the data model. The finance team configures the processes. The tax function receives whatever data the ERP produces and builds compliance processes around it — around its field structure, its timing, its completeness, its limitations. This is the order of operations that has produced every data quality problem the tax function is currently managing: the miscoded supply types, the missing VAT registration numbers, the timestamp inconsistencies, the intercompany positions that never reconcile cleanly. None of these are tax problems. They are ERP design problems that the tax function inherited because nobody asked the tax question at the point of ERP design.

Real-time compliance mandates are reversing this order — not by choice but by consequence. When a CTC mandate requires a digitally signed invoice to be transmitted to the tax authority within seconds of issuance, the ERP cannot produce a non-compliant invoice and fix it later. The tax validation must happen before the transaction is committed, which means the data model must support tax validation from the point of design. The tax function is no longer a downstream consumer of ERP data. It is a design requirement of the ERP data architecture — and the organisations that have not yet restructured the relationship between tax and ERP will discover this through compliance failures rather than through foresight.

The critique this episode makes is of the IT governance model that continues to treat tax as a late-stage configuration requirement rather than a first-principles design input. The ERP data model that is designed without tax at the table will require remediation. The question is whether that remediation happens proactively, during the design phase, or reactively, after the first CTC filing fails.
